Combined roadway concrete combined supporting structure and construction method thereof
The invention discloses a combined roadway concrete combined supporting structure and a construction method thereof. The combined roadway concrete supporting structure comprises anchor cables, anchorrods, reinforcing meshes and gold U-shaped sheds, the anchor cables are arranged at the top of a combined roadway, the anchor rods are arranged on the side wall and the upper portion of the combined roadway, two layers of reinforcing meshes are arranged on the combined roadway, transverse reinforcing steel bars are arranged at the positions where the reinforcing meshes intersect with the anchor cables and the anchor rods, concrete layers are poured on the reinforcing meshes, and the gold U-shaped sheds are arranged on the outer side of the concrete layers. The main purpose of the process is that the grouting and tree anchor processes are adopted to improve the mechanical structure of a rock mass, so that the originally fractured rock mass is agglomerated into a whole through grouting and tree anchor supporting, the mechanical property of the rock mass is enhanced, and deformation is reduced. Concrete pouring avoids the situation that the mechanical property of surrounding rocks is reduced due to weathering and mechanical disturbance, deformation of the surrounding rocks due to external factors is restrained, the compression resistance and shear resistance of a supporting material can be enhanced through concrete pouring and gold U-shaped shed supporting, and therefore the roadway deformation speed is restrained. By the adoption of the supporting mode, a good supporting effect is achieved.
本发明公开了一种联巷混凝土联合支护结构及其施工方法，它包括锚索、锚杆、钢筋网和金U棚，所述锚索布置在联巷的顶部，锚杆布置在联巷的侧壁和上部，在联巷上布置两层钢筋网，在钢筋网与锚索和锚杆相交的地方均设有横向钢筋，钢筋网上浇注有混凝土层，在混凝土层的外侧为金U棚。采用以上工艺主要目的如下：注浆+树锚工艺改善岩体力学结构，使原本破裂的岩体通过注浆+树锚支护凝聚成一块整体，增强其力学特性，减少变形。混凝土浇灌避免围岩因风化以及机械扰动导致其力学性能下降，抑制围岩因外界因素造成变形，通过混凝土浇灌+金U棚支护可加强支护材料的抗压、剪性，从而抑制巷道变形的速度。采取以上支护方式取得了很好的支护效果。
